Patent CA-2438798-A1 (CA)
Inventor: PFEIFER BLAINE
IPC: C12N9/12
Filed: 2002-02-28
Abstract: L'invention concerne l'utilisation d'enzymes qui catalysent la production d'unités d'amorçage et d'extension de polycétides. Elle concerne de plus des modules de chargement modifiés, pouvant recevoir diverses unités d'amorçage telles que des benzoates substitués, et qui peuvent servir à produire des dérivés substitués de produits naturels. Ces enzymes peuvent servir à améliorer le rendement de polycétides produits de façon native ou de polycétides mis au point rationnellement. A l'aide de ces techniques, la synthèse d'un polycétide complet a pu être mise en oeuvre chez <i>E. coli</i>. On peut améliorer la production de polycétides et d'autres métabolites secondaires chez des organismes microbiens en reportant celle-ci après une phase exponentielle et en maintenant des taux de nutriments relativement constants dans le milieu. De plus, on améliore la production de polycétides en prévoyant un système d'expression pour une thioestérase II. Une modification de l'organisme hôte et des conditions de culture permet ainsi d'améliorer la synthèse d'un métabolite secondaire. L'invention permet aussi d'obtenir un organisme hôte qui possède des caractéristiques souhaitables en vue de la production de polycétides et de l'évaluation des résultats de réarrangement génique.

Abstract: A digital video processing method and an apparatus thereof are provided. The method for processing digital images received in the form of compressed video streams comprising the step of determining a region intensity histogram (RIH) based on information on motion compensation of inter frames. The RIH information is obtained based on the motion compensation values of inter frames, and the RIH information is a good indicator of motion information of a video scene. Also, since the RIH information is quite a good indicator of intensity of the video scene, video streams having similar intensities can be effectively searched by searching for similar video scenes based on the RIH information obtained by the digital video processing method.
